Mix a few drops of washing-up liquid, paint and a bit of water in a basin (any size will do). Take a straw and blow through it into the solution until the bubbles rise above the edge of the basin. Place your piece of paper over the top and press down. Lift paper and turn over to see what pattern has been left! By using several different colours, see what interesting patterns can be produced.
